Research Abstract |
We have developed a highly sensitive and specific method to analyze atheronals, cholesterol ozonolysis products. Using this method, we have reported that human neutrophils in inflamed tissues can produce an ozone-like oxidant(s) which can oxidize cholesterol to generate atheronals. Because atheronals impair the formation of an important signal molecule, nitric oxide, by inhibiting nitric oxide synthases and also exert potent cytotoxic effects against a variety of cells including neuronal cells, these could be causative agents for Alzheimer's disease and others.
